Ahoy, matey. If you really must watch an old Disney movie the only ethical way to get one is to pirate it. Otherwise you would be supporting abusive copyright terms that prevent people to sharing something that has become part of their culture for generations. Having a few years of copyright is understandable since companies do need to be able to make money from their investments, but at most it should last one generation (20-30 years) making it 70 years is just obscene.
